Maintenance engineers know the
benefits of monitoring vibration,
however these are not always
appreciated by their work colleagues
and warnings can be disregarded with
catastrophic results. According to
Hansford Sensors, such a
situation occurred recently
where a conveyor pulley bearing
had developed high levels of
wear over a short period of
time.However, it was decided
to keep the machinery
running until a scheduled
maintenance date.

Consequently the
bearing
catastrophically failed,
in turn catching on
fire and resulting in
high costs of damage
to equipment and
putting the lives of a
number of employees
at risk.
